I followed all the steps mentioned on here
to connect to Redshift through Workbench J.
I am not using SSH to connect, so have left SSH settings alone.
When I select Security after selecting Redshift, I see :
Your account does not support the EC2-Classic Platform in this region. Cluster Security Groups are only available when the EC2-Classic Platform is supported. Instead, use VPC Security Groups to control access to your clusters. Go to the EC2 Console to view your VPC Security Groups. For more information, see Amazon Redshift Documentation on Supported Platforms and Managing Clusters in VPC.
My cluster is under a Security Group which has the following Inbound rule :
Type: Redshift
Protocol: TCP
Port Range: 5439
Source: Custom 0.0.0.0/0 (Experimental, just to test,
I will replace this with my IP address)
When I do a Netstat on the host from my machine with -Pn. I get a
Host is up.
PORT STATE SERVICE
5439/tcp filtered unknown
Nmap done: 1 IP address (1 host up) scanned in 2.22 seconds
I have already gone through several similar questions and none of these is working for me.
Double check your Security Group settings:
In the Redshift console, go to the Configuration tab.
Click on the link next to VPC security groups
Should take you to Security Groups in the EC2 console with the correct security group selected.
Select the Inbound tab for the security group and click the Edit button (a dialog box opens).
In the dialog box, click the Add Rule button then:
Select Redshift from the Type dropdown menu
Select Anywhere from the Source dropdown menu
Come back and change this to My Ip once your connection works!
Click the Save button (the dialog closes)
You now have 2 new Redshift rules (0.0.0.0/0 AND ::/0)
Then in SQL Workbench's "Select Connection Profile" dialog:
Click "Manage Drivers" at the bottom left and to add the Redshift JDBC driver.
SQL Workbench configures these automatically but check that Classname is like com.amazon.redshift.jdbc42.Driver and Sample URL is jdbc:redshift://host:port/name_of_database.
Next, configure the connection
Select the new Driver you just created from the drop down.
Copy the JDBC URL from the Redshift console Configuration tab and paste it into the URL field.
Must use the correct port: jdbc:redshift://my-cluster.asdfgh5jk8.us-east-1.redshift.amazonaws.com:5439/my-db
Add your Username and Password
Test the connection! (Bottom right)
Please let me know in the comments if this doesn't work for some reason and I'll help you get it working.

I'm trying to connect to a RDS database (used alongside Elastic Beanstalk) from PGAdmin. From the "Connectivity & security" tab on the db dashboard, I selected the VPC security group and then edited the inbound rules to include a new rule of type "All traffic" with "My Ip" as the source. But adding my ip to the inbound rules does nothing, I keep getting timeout: expired on PGAdmin.
From what I can see on other questions & answers, this seems to be the only required configuration to change, however it does not solve the problem for me.
Does anyone experienced this? What do I need to do to connect to the database from PGAdmin?
Tableau cannot connect to the redshift server.
It displayed:
An error occurred while communicating with Amazon Redshift
Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database.
Error Code: BC42EF73
could not connect to server: Operation timed out
Is the server running on host "redshift-cluster-1.cncrnka9xarv.us-east-2.redshift.amazonaws.com" (3.143.87.206) and accepting TCP/IP connections on port 5439?
I just followed the setup in AWS Redshift Connection with Tableau - YouTube but it fails. What's the reason?
The first thing you should check is the Security Group associated with the Amazon Redshift database, since the video did not reference it.
The Security Group should permit Inbound access from 0.0.0.0/0 on port 5439. Note that this makes your database accessible to anywhere on the Internet, which is not good from a security perspective. However, I couldn't find a reference to the range of IP addresses that Tableau Online uses.
If that doesn't help, then confirm that the Redshift database is in a public subnet. A public subnet is defined as having a Route Table entry pointing to an Internet Gateway.
Solving this error contains 2 steps:
download the AWS redshift ODBC drive from here
Follow what is given in this answer by #JohnRotenstein.
For doing that follow the following steps:
Go to the cluster with which you want to establish the connection.
Then go to "Properties" tab.
Then below there is a section named "Network and security settings" which has "VPC security group" tab and below that there is a link that will redirect you to Security group of the VPC.
Select the VPC and then select the "inbound rules" tab.
There will be a security group where under "source" there will be something starting with "sg-" which means all the connections to redshift from the internet is blocked and only the addressed with this origin will be able to connect with AWS which are EC2 instances.
There click on "Edit Inbound rules".
In the window that opened up, click the "Add rule" button.
Security group rule ID - This you do not need to set
Type - All traffic
Protocol - All
Port range - All
Source - Anywhere Ipv4(not recommended) so it will be set to "0.0.0.0/0".
Description[optional]
Here set the Source to the IPaddress from where the connection request is going to be made and not the above one.
For all other connection queries can be solved by following this link
I have created new EC2 instance set HTTP, HTTPS, SSH anywahere, get Pair, pem file, and tried to connect from window machine using putty.
Putty giving error:
Network Error: Network Error: Connection timeout error
I have tried same procedure from same laptop, same network, same firewall on different AWS account working fine.
Please help me to resolve this issue.
In security gruop I allowed SSH TCP 22 in inbound rule.
To troubleshoot the connection, see: Error connecting to your instance: Connection timed out
Overview:
Check security groups
Check route table
Check Network ACL
Check corporate network
Check CPU load
A timeout error normally indicates that your computer is unable to reach the target computer (as opposed to the target computer rejecting the connection).
Things to check:
The EC2 instance should be running Linux
The security group on the instance should be permitting inbound access on port 22 either from your IP address, or all IP addresses- The EC2 instance should be in a public subnet (defined as a subnet with a routing table entry pointing to an Internet Gateway)
The Network Access Control Lists (ACLs) are preferably unchanged
Your (corporate) network permits SSH access to the AWS network range
Given that you are able to connect to "a different AWS Account", it sounds like your laptop and local network configurations are find. It would have something to do with the instance, security group or VPC configuration.
Have you tried allowing connections on port 22?
Go to your EC2 Instance and click on it so the radio button turns
blue. Scroll down to the bottom and check for Security Groups.
Click on View Inbound Rules and see if Port 22 is enabled. If not
click on the link directly above View Inbound Rules. Screenshot below:
You will see the tabs as shown in the screenshot below:
Click on Edit then Add Rule Button.
Enter the values as shown in the screenshot below:
Click on Save then try connecting to your instance again.
If that does not work, once you go to your EC2 instance, there is a Connect button. Click on that and see a list of possible warnings why you might be unable to connect to your instance.
Check your security group rules. You need a security group rule that allows inbound traffic from your public IPv4 address on the proper port.
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
In the navigation pane, choose Instances, and then select your instance.
In the Description tab at the bottom of the console page, next to Security groups, select view inbound rules to display the list of rules that are in effect for the selected instance.
For Linux instances: When you select view inbound rules, a window will appear that displays the port(s) to which traffic is allowed. Verify that there is a rule that allows traffic from your computer to port 22 (SSH).
For Windows instances: When you select view inbound rules, a window will appear that displays the port(s) to which traffic is allowed. Verify that there is a rule that allows traffic from your computer to port 3389 (RDP).
I am new to AWS. I set up an instance and deployed a Django App on it by following this tutorial
But when I try to access the instance from the browser via the ip or the public DNS it returns 'No data received', 'ERR_EMPTY_RESPONSE'. Any idea where I am going wrong?
Here are the steps I followed to solve this:
Went to EC2 instances
Click on instance
Go to Security Groups column and click on the security group selected.
In the lower panel, select Inbound > Edit > Add Rule
Under Add Rule, select Type as HTTP and Save.
I am new to AWS , I can access EC2 user by putty. Like this how can i connect AWS RDS by PUTTY ?
I have AWS RDS Endpoint , If i try like the below
mysql -h testing.cx2wamr3cbzm.us-west-2.rds.amazonaws.com -P 3306 -u Username -p
I am getting some error like
ERROR 2003 (HY000): Can't connect to MySQL server on 'testing.cx2wamr3cbzm.us-west-2.rds.amazonaws.com' (110)
I think there is a problem with security group.I searched more, but its difficult to understand for me.
I want to create database and assign rights ?
Thanks
RDS is not available to the world by default. It's also generally a bad idea to allow access to the RDS from anywhere except from inside your VPC. I recommend you do the following:
Create a security group that allows access to the RDS over port 3306 from your EC2 instance
Visit https://console.aws.amazon.com/ec2/home#s=SecurityGroups and create a new security group.
Switch to the inbound tab and choose MYSQL from the dropdown.
Erase the 0.0.0.0/0 in the source field then click the input field. It will present you with a list of existing security groups. Choose the one that your EC2 instance belongs to.
Click the apply rule changes button
Assign the security group to your RDS
Visit https://console.aws.amazon.com/rds/home#dbinstances: and select your RDS instance and under the Instance Actions menu select Modify
Change the RDS security group to the one you just created
Make sure to select the Apply immediately option at the bottom of this page
Click Continue and apply the new changes. (the change can sometimes take a couple of minutes)
SSH into your EC2 instance then run the mysql command in your question
